While I'm trying to get to the bottom of this 56kb line problem, I am
wondering just what a "carrier transition" is on a DDS circuit and how
I could get 2000 of them in the space of 2 seconds or so.  I don't
see anything quite like a "carrier detect" on the V35 pinouts.
Is there some sort of pin flapping on a HDLC chip?
